By Amy Pellegrini ; Updated July 18, 2017

Vitamin B6, also called pyridoxine, is a member of the vitamin B complex, which helps the body convert food into energy, according to the University of Maryland Medical Center. Vitamin B6 plays an important role in the body’s metabolic processes and keeps the nervous system functioning properly. The vitamin is also vital to regulating metabolism and maintaining weight loss as it also has a role in making the hormones serotonin, norepinephrine and melatonin, which influence mood and help to regulate the body’s various systems.

Metabolic Function

Vitamin B6 is a vital nutrient for the body’s metabolic processes. According to, vitamin B6 helps synthesize fats from proteins and carbohydrates that enter the body. Vitamin B6 also assists in transporting amino acid and other metallic ions across the cell membranes to keep the central nervous system running smoothly. Pyridoxine is actively used in the processing and metabolism of proteins, fats and carbohydrates, while also helping to maintain healthy sodium and potassium levels.

Thyroid Function

Vitamin B6 also plays an important role in the functioning of the thyroid gland, which is located in front of the neck below the larynx. According to, the thyroid gland is vital to the endocrine system, as it helps to regulate the body’s use of natural chemicals and food to produce energy. The thyroid gland produces hormones that regulate oxygen consumption and the metabolism of tissues, which is aided by vitamin B6. Without a healthy thyroid system, the body is unable to manage energy expenditure appropriately, making it more or less difficult to lose weight and have a properly functioning metabolism.
